AIM Burst.Mikoto attempts to fight the creature as it heads towards a nuclear power plant, but finds her attacks only cause it to regenerate and to grow larger. With the network out of control, the comatose Level Upper users start screaming in pain. Kiyama explains how the creature, called AIM Burst, is the result of the 10,000 Level Upper users' AIM fields and their negative thoughts. With the help of Anti-Skill members Aiho Yomikawa and Tsuzuri Tessō, Kazari manages to upload the cure Kiyama gave her, a song file, which is played all over the city, calming the Level Upper users and weakening AIM Burst. Despite losing its regenerative ability, AIM Burst is still able to use the abilities of the Level Upper victims, emitting their negative thoughts to Mikoto and Kiyama. Mikoto apologizes to the victims for not understanding their feelings, telling them not to give up on their dreams, and shoots a railgun to defeat AIM Burst by destroying its core. Kiyama is taking into custody by the Anti-Skills, still hoping to find a way to cure her students and challenging Mikoto to stop her again if she does not agree with her methods. Kazari rushes over to Ruiko, who, having recovered from her coma and lost her powers, apologizes to her for forgetting what was truly important.
